Ed Cowan and Jordan Silk both scored centuries for Tasmania but South Australia were able to hold on for a draw on the final day of their Sheffield Shield match in Adelaide. Phillip Hughes and Tom Cooper both made half-centuries in South Australia's chase of 285 but regular wickets kept the Redbacks from reaching the point at which they could realistically push for victory.

At 2 for 130 in the 24th over they had some hope but the loss of Hughes, who was caught off the bowling of Xavier Doherty for 67, sparked a collapse. James Faulkner picked up two quick wickets before Cooper and Tim Ludeman steadied, and when time was called, Cooper was unbeaten on 74 from 94 deliveries, with Ludeman on 18.

Earlier, Silk and Cowan carried on from their overnight half-centuries to both reach triple figures before Ben Dunk (72 off 54 balls) and Faulkner (53) helped steer the total up to 7 for 390 before the declaration came. Cowan made 123, his first century at first-class level since he was dropped from the Test side during the Ashes tour of England.

Silk, 21, continued his outstanding start to the summer - he has now scored two hundreds in the first four Shield matches of the season and averages 46.12. Silk has also had a remarkable beginning to his first-class career - he debuted in March and has already scored four hundreds and three fifties in his first nine games.
